I downloaded the trial version of Supermetrics with the hope of buying if I can achieve a couple of things. One being the capability to merge Google Analytics data with a custom query in BigQuery. The goal is to create aliases for event labels in Google Analytics.
you can make queries from both data sources but combining it needs to be done manually. I suggest Supermetrics for Google Sheets for this so then you'll have all spreadsheet capabilities to do that, as well as access to both data sources among dozens of others.
Thank you - but to use Google Sheets I will be limited to the 2 million limit..
That's true. Unfortunately we have no control over that.
